Thanks to its higher boiling point, viscosity and specific gravity, DEG (Diethylene Glycol) has similar applications to ethylene glycol but has a higher molecular weight.

Utilised in the manufacture of drywall joint compound, printing ink, furniture and shoe polishes, thermoplastic polyurethanes and emulsifiers, DEG is ideally suited to applications that demand hygroscopicity, lubrication and low volatility.

The specialised uses of DEG also highlight its differences from ethylene glycol, with its impressive reactivity and solubility providing the basis of many applications. Colourless with low volatility, DEG has no odour, other than a slightly sweet smell at high vapour concentrations. It is also completely miscible with water and many organic liquids.
